• The graph of a quadratic function is a parabola.

• Use the axis of symmetry to help you graph a parabola. Graph the right or left half and then reflect the graph across the axis of symmetry.

• The maximum or minimum value of the function occurs at the vertex. Use the formula for the vertex to find the maximum or minimum.
